Observation:
I also observed that the zimbra admin page shows wrong information. Although the value was changed from zen.spamhaus.org to sbl.spamhaus.org and working like this, the admin console still shows the RBL list of zen.spamhaus.org

That is actually not the case for me. If I make a change via CLI as so:

Code:

zmprov mcf -zimbraMtaRestriction "reject_rbl_client xbl.spamhaus.org"

OR

Code:

zmprov mcf +zimbraMtaRestriction "reject_rbl_client sbl.spamhaus.org"

The admin console updates correctly. Vice versa...if I make changes via the admin console, they reflect as entries like the above. The trouble I was having earlier in the thread seems to have been a fluke.
